Here's mine. It's a mix of my faves and what I think other people would like. There are several I suspect would make this list but I haven't played them yet, like the Disworlds, the rest of the Tex MurphysByzantine, The Neverhood, Callahan's, Reah, etc.

To date I have 52 or 53 games on my closet shelf that I will keep and play again....and you want to limit me to only 15? Well......OK - here goes (in alphabetical order not order of most favorite):The Arrival; Black Dahlia; Byzantine The Betrayal; Dark Side of the Moon; Frankenstein Through The Eyes of a Monster; Gabriel Knight 1; Gabriel Knight 2; Gabriel Knight 3; Grim Fandango; The Longest Journey; Morpheus; Neverhood; Riddle of the Sphinx; Shivers I; TemujinLove, Betty Lou

A few of these could probably be replaced, but I will wait for final judgement till I have completed more of the newer (and older) ones. I still have dozens loaded, and a big bunch in some stage of play. But as everyone SHOULD play these anyway.....................
